Abstract
Android is a platform that is very vulnerable to hacked by bad people to steal users' data intentionally
or unintentionally [1]. To deal with data disturbances it is necessary to use cryptography [2], one of which is
Playfair Chipper. Playfair's cryptographic algorithms are currently being developed with various types of matrix
table modifications, ranging from changes in matrix size, or changes in the encryption process steps. The results of
applying the Playfair combination and modification algorithm with the Linear Feedback Ship Register (LFSR) for
securing data on the Android platform. Testing the application of the results of the Playfair algorithm modification
using the Avalanche Effect can be concluded that the resulting ciphertext has a high complexity.
